Sometimes lag isnt always attributed to internet speeds. You may have malware that can cause issues, i use Malwarebytes and Spybot both to keep things clean. Make sure you dont have wires plugged in to the router that arent plugged into anything. Cable providers not using fiber may be more vulnerable to upstream and downstream noise issues, usually youll see very erratic speed tests when that occurs.

Like stated above, you get more bang for your buck from a desktop. The laptops you are looking at have older processors in them, the i3 has a second generation chip, while the amd5000 also is old. What price range you looking?
